The 21-month extension is worth $2.5 million, and is the fourth extension of Volkert's contract with the board since the company began working with the district in 2003. Since the original contract was signed, the district has paid Volker $19.4 million to run its capital program.

The district is still in the middle of its $405 million capital program from the Jefferson County 1-cent sales tax, which includes dozens of new schools and renovations to existing ones.
